Up close and personal. Hairy. Tubes. Gourd-like forms. This is actually two kinds of kelp tangled up in each other: the Bullwhip or Elkhorn Kelp (Pelagophycus porra) is the one with the bulbous thing and the hairy one is Feather-Boa Kelp (Egregia menziesii.)
Now, don’t you feel ridiculously erudite and well-informed? There is also a Giant Bladder Kelp that we see quite often. It has leaf-like blades and is a common source of emulsifiers in many foods. I wonder if I could find it listed on the ingredients label (as ‘alginates,’ possibly?)
Cool stuff. We have a book called Life Between the Tides that helps me out with this sort of thing.
